Still busy with Algebra but I am very lucky to have Barb Wedow from the Math lab helping me get through things. I went to do some home work and on the way home my beautiful 2000 Audi TT died on the way home. The good news is that it is just the alternator. So this post is admittedly off topic..but a 2000 year car with only about 31,000 miles is a bit of piece of automotive archaeology. Standing and waiting for a tow truck in 100 degree heat on pavement was not as nice as standing at our dig site.
